and the like, of which the following is a specification.

This invention relates toimprovements in taps, valves, cocks and the like using a resilient ball as the valve member, and my object is to devise a construction in which the valve member, while entirely free, will be certain to properly seat on its seat, in which the valve member will be subjected to a minimum amount of wear, and in which the valve member may be quickly replaced with a minimum of inconvenience.

I attain my object by means of the constructions hereinafter described and illus-' trated in the accompanying drawlng, which is a cross section of a water tap constructed in accordance with my invention.

1 is the casing of the tap provided with the usual inlet opening 2 and outlet nozzle 3. The casing is open at its upper end, which opening is closed by a screw cap 4. Through this cap extends the spindle 5, provided with the usual handle 6. .The upper portion of the inside of the casing is threaded to receive threads formed onthe enlargement 7 of the spindle. I

Extending from one side of the casing above the inlet 2 to the lower side of the outlet 3 at the other side of the casing is the. partition 8. This partition has an opening formed therein through which a depending portion 9 formed on the lower end of the spindle is adapted to pass. This depending portion 9 has a valve displacer 10 secured to its lower end in such a manner that the displacer is free to rock slightly.

in all directions. 7 a

11 is the valve member, preferably formed of rubber or other resilientmaterial, which will be located in the casing below the partition 8. To enable the valve member to be easily placed in'position, I form an opening in the lower end of the casing, which opening is closed by a screw plug 12. From the drawing it will be seen that the portion of the casing below the partition 8 is approx1- mately spherical and that the end of the plug is dished out to follow the general shape of the sphere. The threaded portion of the plug 12 has a plurality of notches 1'3" I I formed therein.

Suitable washers will be provided within the cap 4 and for the plug 12.

Specification of Letters Patent. P t te g, 17,

the tap below the partition 8 is very important, as there are no corners in which the valve member may lodge to prevent its proper seating to close the opening in the partition, and further there are no sharp edges to damage the valve member.

The valve member, it willbe noted, is free to revolve in any direction, and thus any wear w1ll be distributed over itsentire sur-. face, thus avolding wear in spots.

The object of the notches 13 is to give the water a better opportunityv of getting below the valve member to force itv up against its seat on the lower side of the partition 8Q j g a As the valve seatis on the lower side of thepartition 8, it will be seen thatthe spin- 1 die 5 has to be operated in the reverse direction to the ordinary tap to open and close the tap, that is, the spindle will be screwed down to force the valve member from its seat, and up to allow the valve member to return to its seat.

Should it become necessary at any time replace the valve member, it is merely necessary to remove the plug 12, when the valve member will fall out. To insert. the new valve member, it is placed in the dished end of the plug and the plug then screwed intoposition.

From the above description, it will be seen that I have devised a construction which will satisfactorily attain. the objects or" my invention as set forth in the preamble of this specificatmn.

' While the invention is shown and described as applled' to a watertap, it will be understood, of course, that the inventionis also applicable to taps of other kinds and valves, cocks, and faucets of'various kinds.

What]: clalm as my lnvention 1s In a valve, the combination of a casing having inlet and outlet connections extending from its sides and an opening in its lower end; a partition dividing the casing into upper and lower chambers and extending from the upper side-of the inlet connection to the lower side of the outlet connection, said partition havinga passage formed therein having avalve seat on the under side said lower chamber being-substantially having a' flat lower surface; and a dished spherical; a resilient ball valve member plug closing the Opening in the lower end of loose in the lower chamber adapted to-be the lower chamber, said dished plug having seated against said seat; and a spindle opa plurality of notches formed in its edge.
